Title: Control valve for liquid flow, with accurate setting - has switching element fitted in blocking direction of controller operating coaxially
Inventor: SPOHR HANSWERNER ING GRAD
IPC: F16K37/00
Filed: 1980-11-06
Abstract: The control valve is for a fluidic medium, where the moving control element has exact positional control even when the fluid flow contains metallic impurities. The movable control element is in a housing joining two pipe sections and releases or blocks more or less liquid. Control is effected electrically or electronically where a circuit is kept closed and the valve is in the blocking position. The switching element (15) mounted in the blocking direction of the control element (12) can move coaxially with the direction of motion and relative to the control element. The movement is limited and closes the circuit as soon as the control element is in the blocking position.

Title: Domestic appliance door seal - with corners of softer elastomer bonded to harder straight sections
Inventor: KLEMENT JOHANN
IPC: F25D23/08
Filed: 1980-12-03
Abstract: The sealing elements for the door of a domestic appliance, e.g. a baking oven, washing machine, dishwasher or refrigerator, are made of a vulcanisable elastomer laid into a groove with L-shaped edges at the door corners. The material for the straight sections of the seal have a Shore hardness of 60. The corners are made of a softer material with a Shore hardness of 50 which is injected into a vulcanising mould and joined to the straight sectons by vulcanisation. This creates a more reliable seal than straight sectons, abutting in a joint, or laid-in seals which tend to bunch up on the corners.

Title: Prodn. of sliding clasp fastener band by injection moulding - of links onto strip with further compaction of excess material before removal
IPC: B29D5/02
Filed: 1980-12-10
Abstract: A strip or band for a sliding clasp fastener is produced from a support strip by injection moulding onto this strip the closure elements or links of thermoplastic material; this is done using a continuously revolving mould wheel contg. the cavities for forming the links and a moulding belt, running on the wheel, contg. openings, opposite to the cavities, through which the thermoplasticised material is forced by an injection head covering several cavities. The effect of this (conventional process is to produce a skin of thermoplastics material on the outer or rear face of the belt; this skin moves along with the belt and is later peeled off it. Behind the injection nozzle the skin passes through an after-compacting zone (NV), in which while still soft it is subjected to pressure acting onto the wheel. In this after-compacting zone also, the skin is cooled to below its solidification point. By maintaining full compaction for a period after injection, better moulded links are produced and marks due to shrinkage of the material in the mould cavities are eliminated.

Title: Beverage, containing fructose and vitamin C, for the accelerated reduction of the blood alcohol level, and process for the preparation of the beverage
Inventor: LEONHARD WALDEMAR
IPC: A23L2/38
Filed: 1981-04-15
Abstract: It is known that mixtures of fructose and vitamin C reduce the blood alcohol level in an accelerated manner. Practical application of this finding has failed hitherto because of the unpleasantly sweet taste of such mixtures. It has now surprisingly been found that addition of quinine completely changes the repellently sweet taste of a beverage containing fructose and vitamin C and gives a slightly bitter dry beverage which is very good to drink during and after alcohol consumption. The present invention describes the composition of such a beverage and a process for the production thereof.

Title: Internal combustion engine with reciprocating pistons and a crankshaft
Inventor: EMMENTHAL KLAUS-DIETER DR ING
IPC: F02B75/18
Filed: 1981-05-21
Abstract: The invention relates to an internal combustion engine with reciprocating pistons and a crankshaft with at least one balance weight driven in oscillating fashion by the crankshaft via a crank mechanism. To make it feasible for the balance weights provided for balancing the free inertia forces and moments of inertia to be assigned additional tasks, the balance weight is to be designed as a piston (12), sliding in a cylinder (5), of a piston pump which supercharges the cylinders (3, 4) of the internal combustion engine. In a two-cylinder in-line four-stroke internal combustion engine with two pistons connected to the crankshaft via crank pins arranged in phase, a third cylinder (5) designed as a supercharging pump can then be provided, this cylinder being arranged diametrically opposite the cylinders (3, 4) of the engine relative to the axis (15) of the crankshaft and being provided with an associated piston (12) which can be driven by a crank pin (14) of the crankshaft (2) situated diametrically opposite the crank pins (10, 11) of the engine pistons (6, 7). The frictional losses which arise between the piston (12) forming the balance weight and the cylinder (5) can be reduced by the provision of a hydrostatic sliding bearing (18) connected to the lubrication circuit of the engine. <IMAGE>

Patent DE-3134846-A1 (DE)
Title: Method for improving the signal-to-noise ratio of electric signals
Inventor: BENGER JOSEF
IPC: H04B1/10
Filed: 1981-09-03
Abstract: In a method for improving the signal-to-noise ratio of electric signals, in which the signal received by an antenna and amplied in a receiver is rectified and conducted via a low-pass filter whose upper cut-off frequency is substantially higher than the bandwidth of the useful signal but lower than the intermediate frequency of the receiver, or is mixed down into the baseband or is transformed into the frequency range, the original signal thus obtained is sampled at a frequency which is higher than twice the value of the highest occurring signal frequency and digitised. Either in real time or after intermediate storage, data reduction is carried out at an arbitrary time in conjunction with successive data records respectively having n values, the data records being used in spacings of 1<k<n and n being an arbitrary number greater than 1, in such a way that the smallest of these n values in each case is determined and the signal thus extracted, consisting of the sequence of the minimum values of the data records, is fed continuously, in real time or after intermediate storage at an arbitrary time directly or after digital-to-analog conversion to a display device or a signal processing device, as is customary with conventional receiving systems.

Inventor: MUSCHELKNAUTZ EDGAR PROF DR IN
IPC: C03B37/06
Filed: 1981-11-12
Abstract: In the production of fibers by blast drawing in which primary filaments are produced from a liquid stream, reduced to fibers and drawn on passing through a draw nozzle by drawing gas streams flowing substantially parallel to the primary filaments, the improvement which comprises surrounding the drawing gas streams over at least part of their length and inside the draw nozzle in the direction of flow by parallel boundary gas streams having at most the same flow velocity as the drawing gas streams. Advantageously the parallel boundary gas streams are formed by that part of a circular flow produced on both sides of the drawing gas stream which is in contact with the drawing gas stream, the flow velocity of the parallel boundary gas streams amounts to between about 60 and 80% of the velocity of the drawing gas streams, the drawing gas streams having a velocity of from about 360 to 500 m/s, the volume flow of the parallel boundary gas streams amounting to between about 20 and 60% of the volume flow of the inlet stream, the drawing gas streams and the parallel boundary gas streams being driven by a pressure gradient generated by power jets in the draw nozzle. A corresponding novel draw nozzle is provided. The inner walls of the nozzle do not undergo the erosive/abrasive wear characteristic of other draw nozzles.

Patent DE-3217131-A1 (DE)
Title: Adjustable shutter hinges
Inventor: POERSCHKE ECKHARD
IPC: E05D7/04
Filed: 1982-05-07
Abstract: The invention relates to shutter hinges for doors, gates, hatches, etc., on which the distance between the pivot point and the pivotable part can be adjusted. The shutter hinges are to allow a simpler mounting of doors, gates, etc. and, moreover, subsequent readjustment. Shutter hinges have hitherto been produced only as a rigid piece which can be shifted only by changing the screws over. The object on which the invention is based is to allow a quick and simple setting of doors, gates, hatches, etc. The object is achieved, according to the invention, in that three versions are offered, as required, on the door, gate or the like. In version A, the pivot-point distance is adjusted in that the shutter hinge is doubled over a portion at the end where the pivot-point lug is attached. The doubled hinges are screwed through long holes, so that the shutter hinge can be lengthened or shortened here. In version B, the pivot-point distance is varied by attaching to the end of the shutter hinge a threaded piece with an internal thread, into which the pivot-point lug attached to a threaded piece can be screwed or from which it can be unscrewed. In version C, the pivot-point distance is varied by angling the shutter hinge at 90 DEG  at the end. In the angled piece is made a long hole, through which a threaded piece with the pivot-point lug is screwed. The pivot-point distance can be varied by rotating the nuts. Example: if a two-wing wooden gate sags in the middle after some time, the gate can be set straight again by shortening the pivot-point distance of the two upper shutter hinges.

Title: Undercarriage frames for vehicle cranes
Inventor: DIEDRICH HELMUT ING GRAD
IPC: B66C23/62
Filed: 1982-07-01
Abstract: Undercarriage frames for vehicle cranes of open frame construction having frame halves constructed as canted longitudinal girders exhibit sufficient dimensional stability only in the case of light to moderately heavy crane vehicles. To be able to use undercarriage frames of open frame construction even in the case of heavy vehicles, without the need for greater wall thicknesses which increase the dead weight undesirably, the conventional single-skin design of the longitudinal girders (2) is retained only in the regions of the frame which accommodate the drive motor or the gears. In the remaining regions, the longitudinal girders (2) are strengthened by means of box-type inserted profile sheets (8). The profile sheets (8) can be constructed as effective profiles. A further improvement in the dimensional stability is achieved by a mutual connection of the frame halves, strengthened in this way, at certain points of the frame. <IMAGE>
